Then, illustrate that according to Fig. 4 the inside of the video disc carriage 1 in the disk apparatus of the present invention constitutes summary.Be depicted as the state of the bottom 15 of dismantling with figure, be equipped with drive unit A in central authorities, this drive unit A is with spindle drive motor 3, the magnetic head unit 4 that laser disc rotation is driven and makes gear motor 16 that this magnetic head unit 4 moves back and forth along the radial direction of laser disc and gear unit 17 be the main body formation.And, be equipped with in the front end corner of video disc carriage 1 one and withdraw from/locking device B, in side arm 1c, be equipped with slide block device C.
Aforementioned magnetic head unit 4 floats its two ends and is provided with in guiding shift unit 18, the tooth 19b that is fixed in the tooth member 19 of this magnetic head unit 4 moves under the guiding of the guiding ditch 20a of screw axis 20 and action back and forth.Fig. 6 is that the expansion of the major part of this formation is represented, the main body of tooth member 19 and supporting member 21 utilizes screw to be fixed on the unsteady magnetic head unit 4 that is arranged on the guiding shift unit 18 simultaneously.
Therefore, when tooth member 19 and supporting member 21 are carried out one fixedly the time to magnetic head unit 4, as shown in Figure 8, the state that the following lappet 19a of tooth member 19 pushes with the support chip 21b of beared part 21 gives forwards thrust by pressing tablet 21a.Whereby, the tooth 19b of following lappet 19a becomes solid and reliable to the interlock of the guiding ditch 20a of screw axis 20, can prevent down that the extruding of lappet 19a is risen.On the other hand, when utilize screw axis 20 impose with following lappet 19a down by power, and make down lappet 19a when being shifted shown in the dotted line of figure, column 19e is also pressed by this time lappet 19a, and with the guiding shift unit contact, the displacement of lappet 19a is restricted under this position.
Like this, by supporting member 21 combination is fixed on the tooth member 19, the tooth 19b that can fully prevent down lappet 19a comes off from the guiding ditch 20a of screw axis 20, and can tackle the high speed of the visit of 4 pairs of laser discs of magnetic head unit.That is, because along with the raising of the recording density of laser disc, the frequency that magnetic head unit 4 moves back and forth increases and is high speed, follows this situation, the rotational speed of screw axis 20 also improves.
In this case, by the guiding ditch 20a of screw axis 20 the tooth 19b of lappet 19a is down applied rapid driving force, this moment upward or below produce component, make down lappet 19a extruding rising or be pressed, the interlocking pattern of tooth 19b and guiding ditch 20a shoals, and increases the danger that comes off.And this phenomenon shows significantly especially in the terminal of the guiding ditch 20a of screw axis 20, the probability height that tooth 19b comes off from guiding ditch 20a, but by adopting above-mentioned formation can prevent this phenomenon fully.
Then, the formation that is used for said spiral axle 20 is rotated the gear unit 17 of driving is described.In known techniques, the formation of the gear unit of this part is to realize by the handwork that the gear shaft with each gear is inserted in the formed dead eye of gear framework.But, utilizing the occasion of this operation, usually the denture of synthetic resin institute moulding is caused the probability height of damage, when in gear unit, having impaired gear, can produce the big problem of so-called searching (seek) change of tune.
Therefore, in disk apparatus of the present invention, adopted formation as shown in Figure 9.In with the formation shown in the figure, gear unit 17 is combined to form by 3 monomer gear G1G2G3's, and gear G1 is fixed on the output shaft of thread motor 16.On the other hand, be fixed with gear G2 on the screw axis 20 of the conveyed object of the revolving force that becomes aforementioned threads motor 16, it is inserted in the dead eye that forms on the gear framework.Under such state, fall in the bearing ditch 24 that on gear framework 23, forms by gear shaft gear G3, can load gear G3 like a dream.
Promptly, in known technology, the filling of gear G3 is that gear shaft is inserted in dead eye, so the horizontality of the gear in the time of can not keeping loading causes damage to denture, but utilizing the occasion of above-mentioned formation, can simultaneously keep the horizontality of gear G3 simultaneously to load, and gear G1G2 follows the filling of gear G3 to produce driven and is rotated, thus can in addition excessive load to each other denture, can avoid the danger of gear unit 17 damage when assembling whereby.
In the occasion of the formation of utilizing said gear unit 17, the gear shaft of gear G3 is to 24 one-tenth in the bearing ditch state that is rotatably assorted, so in order to prevent that it from coming off, cover plate 25 is installed.This cover plate 25 at one end is formed with tapped through hole 25a as representing with inverted status among Fig. 9, is formed with engaging claw 25b in 2 positions of the other end.When the end with this cover plate 25 utilized screw 26 to be fixed in gear framework 23, an engaging claw 25b of the other end was bonded among the fenestra 23a that forms on the gear framework 23, and another engaging claw 25b is bonded on the 23b of portion of joining section rank.And, when aforementioned each engaging claw 25b is engaged in aforementioned fenestra 23a and the joining section rank 23b of portion, annotate shown in the figure as the circle of Fig. 9 in the dip plane that the corner of (undercut) portion of sinking of engaging claw 25b forms, contact with the top rib portion of the bonding station of gear framework 23.Whereby, cover plate 25 can not float and positively fixes, so even propagated from the vibration of thread motor 16, gear unit 17, cover plate 25 can excited oscillation yet and produced noise.
Then, withdrawed from disk apparatus of the present invention adopts/formation and the action form of locking device B describe.This withdraws from/and locking device B is used for fixing video disc carriage 1 blocked state or remove this stationary state and make the device that video disc carriage 1 can be unloaded in casing box 10, as shown in figure 10, constitute by self-sustaining type solenoid 27, relieving rod 28, securing rod 29, ejector return pin 30.
To be tops of making a pair of yoke (yoke) 27a27b be inserted to about position intermediate and be fixed by the rear end of field coil 27c27d aforementioned self-sustaining type solenoid 27.And, at the end of aforementioned yoke (yoke) 27a27b permanent magnet 27e is installed, form horseshoe-shaped magnetic circuit whereby.On the other hand, be inserted with the operation strip 27f of magnetic material on the top of field coil 27c27d, it can carry out forward-reverse and move.
So under normal condition, by the magnetic force that utilizes the formed magnetic circuit of aforementioned permanent magnet 27e, aforementioned operation strip 27f is held with a kind of state that is attracted.And, produce and the opposite magnetic field, magnetic field that utilizes permanent magnet to produce with terminal by the external dc electric current from field coil 27c27d, the magnetic field that utilizes aforementioned permanent magnet 27e to produce is eliminated, remove constraint to operation strip 27f.Because this operation strip 27f is connected with pin 28a on being fixed on relieving rod 28, so synchronous with the forward-reverse of operation strip 27f, relieving rod 28 also along continuous straight runs moves back and forth.In addition, self-sustaining type solenoid 27 utilizes screw clamp to be fixed on the video disc carriage.
